In the Blockchain industry, both Hyperledger and Ethereum have spurred innovation. These two major open-source Blockchain platforms have not only recognised a wide range of blockchain applications already in use, but they are also inviting Blockchain Developer from around the world to help them create these Blockchain-based frameworks and tools.

What precisely is Ethereum? Ethereum is a decentralised, public, and distributed computing platform that is primarily used to execute smart contracts. Each network member (node) has access to the same copy of the Blockchain network because it is a decentralised platform. When a new block is added to the Ethereum Blockchain, it is also added to the global copy, which all network nodes share.

What is Hyperledger exactly, and how does it work? Hyperledger, an open-source Blockchain project, was founded and is hosted by the Linux Foundation. However, it is a worldwide collaboration involving major financial, banking, IoT, technology, and manufacturing firms. It's a permissioned Blockchain platform that allows you to create custom Blockchain apps to match your specific business needs.

The Platforms Ethereum and Hyperledger Serve a Purpose Ethereum: The Ethereum Virtual Machine was built specifically to run smart contracts (EVM). It also enables the development of decentralised apps (dApps). Hyperledger is a cross-industry collaboration platform for developing high-performance, trustworthy blockchain technology. Users can also use this technology to develop their own blockchains for their own needs. It's important to remember that Hyperledger is a B2B platform, whereas Ethereum is a consumer-facing platform.

The operation mode of Ethereum is public, which means that anyone can utilise the Blockchain network without requiring any authorization. Hyperledger, on the other hand, is a private Blockchain that may only be accessed by permitted individuals. To put it another way, the network is limited to a select group of individuals who have granted their permission.

Influence of peers Each peer in Ethereum has a role, which implies that a transaction must be completed by a large number of nodes, posing scalability, privacy, and efficiency concerns. Hyperledger, on the other hand, is a distributed ledger technology (DLT) that doesn't require every peer in the network to be notified before a transaction can be carried out.

Level of Confidentiality in Each When we talk about Ethereum, we're talking about a public network, which implies that every peer on the Blockchain network may view and access all transactions. Hyperledger, on the other hand, is private and permissioned, meaning that only authorised members have access to the network's transactions.

Mechanism of Consensus Proof-of-Stake (PoS) consensus is used in Ethereum, and it requires all nodes to agree. Hyperledger, on the other hand, uses a one-of-a-kind consensus algorithm. In this case, nodes can choose between a no-consensus and an agreement technique. The Robust Byzantine Fault Tolerance (RBFT) consensus mechanism, for example, is used in Hyperledger Indy.

Programming Languages of Various Types Ethereum smart contracts are written in Solidity, Ethereum's native programming language. Golang is used to write Hyperledger smart contracts.

Bringing the discussion to a conclusion Now that we've covered all of the major distinctions between the two, the question is: which is superior? It's important to realise that there's no one-size-fits-all solution to this problem, and each of these platforms serves a distinct purpose. Ethereum may be used to build decentralised applications (dApps) and smart contracts that can perform a wide range of tasks. Hyperledger, on the other hand, is a fantastic platform for building business-to-business apps.

After the success of Bitcoin and cryptocurrencies as defined by ernesto.net, the attention fell on blockchain technology. The technology was slowly proving to be very important and according to some, it is defined as the best thing that has happened since the internet revolution. However, just like any technology, it is not stationary but continues to evolve and to be refined. Along the way, something known as Hyperledger Sawtooth was born.

The development of Hyperledger Sawtooth

Hyperledger Sawtooth is the latest edition from the Hyperledger community, the creators of Hyperledger Fabric. The project began at Intel Labs in 2014 through a research project known then as Sawtooth Lake.

The project wanted to address security and scalability issues affecting the then growing adoption of Bitcoin. It also wanted to find ways to migrate blockchain technology to the enterprise. In 2016, a milestone was achieved when the Proof of Elapsed Time consensus algorithm was delivered as a free and safe alternative to Bitcoin’s Proof of work consensus algorithm.

Intel then made Sawtooth available to Hyperledger Training, which was just getting started at around that time. The Hyperledger community grew significantly and several organizations such as Amazon Web Services, Wind River, Ericsson, Huawei, IBM, Microsoft Azure, Bitwise.io, Cloudsofts, Context Labs, Active Ticketing, Dot BC Media, and Hacera joined the ship.

What is Hyperledger Sawtooth

Hyperledger Sawtooth is a modular enterprise distributed ledger used to build, deploy, and run enterprise blockchain apps and networks. It was wholly designed to keep enterprise blockchains as decentralized as possible while improving the safety of smart contracts.

Sawtooth distinguishes itself from traditional blockchains in the sense that it is highly modular. This gives companies the opportunity to make customized policies that are tailor-made for the specific enterprise.

Another major advantage of Sawtooth is that its core system is differentiated from the application domain. Moreover, it is flexible and uses the principles of a black box. It is not rigid on the language that developers can use to develop applications and can easily formulate rules that are specific to the business needs. Moreover,  the developers can create applications without knowing how the core system was designed.

Hyperledger Sawtooth has the following key features:

Dynamic consensus

Ethereum support

On-chain governance

An advanced engine for transaction execution

Multiple language support

Dynamic Consensus

Different blockchain platforms use different but fixed consensus algorithms. Bitcoin uses the proof-of-work system. The network users compete to solve a particular cryptographic problem. Whoever solves the problem is rewarded with Bitcoins.

Another consensus algorithm used is the proof-of-stake. It is based on the proof of ownership. Another consensus algorithm used is the proof-of-elapsed-time.

What makes Hyperledger Sawtooth so special is that it is not hardwired to use only one consensus algorithm. It can use any system and interchange between them. Each system has its own advantages and disadvantages. Hyperledger Sawtooth users can choose a consensus algorithm that is good for their specific needs.

Smart contracts

Smart contracts are small programs that execute business logic. Their functions are similar to that of a computer. They accept an input, process and execute it, and give out an output. They live on a layer of the blockchain where use cases that are specific to the particular business case are required.

Although Bitcoin is largely responsible for the limited use of smart contracts, it is Ethereum that pioneered their use. The smart contracts that are included in Sawtooth are:

Settings – provides a platform for the storage of configuration settings

Identity – deals with the permissions on the blockchain

Validator registry – registers ledger validators and components important for the security of Proof-of-elapsed time.

On-chain governance

The ‘settings’ option makes on-chain governance possible on Hyperledger Sawtooth blockchain. This allows users to store on-chain configuration settings such as the consensus algorithm used.

Multiple language support

Developers can build smart contracts using several languages including Python, Javascript, C++, Rust, and Go.

Advanced engine for transaction execution

Parallel processing of transactions in order to speed up the creation and validation of blocks
